Abstract
An evaporator includes a maple sap evaporating pan in fluid communication with a maple syrup forming pan, a fire box in gas communication with gas circulating adjuncts, a flue stack and chimney and an auxiliary reservoir for pre-heating the sap prior to entering the maple sap evaporating pan. The auxiliary reservoir consists of a housing defined in the flue stack with an inlet for receiving cold sap. A series of horizontally spaced open end vertical tubes extends through the housing, each tube including a lower inlet receiving from the adjuncts flue gases that circulate through and heat the tubes and an upper outlet allowing the gases to exit through the chimney. Hence, cold sap received in the auxiliary reservoir is first heated by contact with the hot tubes.

In an evaporator having a maple sap evaporating pan in fluid communication with a maple syrup forming pan, a fire box in fluid communication with a set of horizontally disposed gas circulating adjuncts, a flue stack and chimney successively, the improvement comprising an auxiliary reservoir for preheating sap prior to entering said maple sap evaporating pan;
- said auxiliary reservoir consisting of a housing disposed in said flue stack and including an inlet for receiving cold sap in said housing;
- a series of spaced open end vertical tubes extending through said housing, each tube including a lower inlet receiving flue gases from a gas circulating adjunct disposed underneath the auxiliary reservoir for circulation through and heating said tubes and an upper outlet for exiting said bases to said chimney whereby cold sap received in said auxiliary reservoir is heated by contact with said heated tubes;
- said housing further including an outlet allowing heated sap to be directed to said maple sap evaporating pan.
